LIQUID-STRAINER.

Specification of Letters Patent.

Application filed lipril 15, 1909. Serial No. 490,015.

To all whom it may concern:

Be it known that I, MIGUEL ARRUEBAR- RENA, a citizen of the Republic ofCuba, and a resident of Cienfuegos, in the Province of Santa Cla a andRepublic of Cuba, have invented a new and useful Liquid-Strainer, ofwhich the following is a full, clear, and exact description.

The principal object which the present invention has in view, is toprovide a con tinuously acting filter for sugar syrup, which may beoperated with the minimum of power and which may be readily cleaned.

One embodiment of the invention is shown in the accompanying drawingswherein like characters of reference indicate like parts in all theviews.

Figure 1 is a cross section of a filter constructed in accordance withmy invention, portions of the side walls being cut away to show the gearwheel at the farther side of the same; Fig. 2 is a longitudinal sectiontaken on the line 22 in Fig. 1; Fig. 3 is a detail view of the hingeconstruction provided for the cleaning door; and Fig. 1 is a detail viewof the locking device employed for the cleaning door.

The filter herein described is employed to receive the heavy crudeliquor of the first boiling of the sugar cane, there being contained inthe heavy, viscous mass, debris and foreign matter of various kinds. Thefilter herein shown when in use is suitably mounted above a reservoir orsuitable receptacle. The major part of each of the members of the filteris constructed from perforated metal, the perforations being formed to asize adapted to pass the liquor and to retain the debris. To assist inthe filtration a column of water is introduced into the filter, whichdissolves the syrup and prevents clogging of the openings in the metal.

The construction consists primarily of a cylindrical drum held in shapeby rings 5, and the drum is rigidly suspended by means of rods 6 and 7,the rods 7 being mounted pivotally on a horizontal extension of the rod6. The rod 6 passes horizontally between lugs 8 bolted to a side wall 9.The wall 9 is provided with a central opening 10, and extended throughthe opening 10 is the end of a. chute 12. The rods 7 are pro vided witha horizontal extension 13 adapted to swing into recesses 14 formed inthe end of the said chute 12, and it is by means of this constructionthat the said chute is prevented from rotating.

It is understood that the drum and the chute heretofore described remainstationary, or fixed in position, the chute extending through and beyondthe opposite wall 17 of the said drum. At the opposite end of the chute12 is formed a hopper 15, to which are secured supporting rods 16, uponwhich the filter is mounted. The chute 12 is completely cylindrical atthe end where it passes through the wall 17 of the filter, and is morethan half completely cylindrical for the remainder of its length. Thesaid chute forms a bearing for collars 11 and 18, to the latter of whichis bolted a gear wheel 19. The collar 18 and the collar 11 are rigidlysecured to the plates 20, there being as many of these plates as it isthought desirable; in the present instance the number selected is four.The outer ends of the plates are curved to form scoops, and these endsmove close to the cylindrical wall 21 of the drum, the bent form of theends of the plates 20 being maintained by tie rods 22.

The chute 12 is divided within the drum by an inclined partition 23,designed to convey the debris beyond the end of the chute 12. Below thepartition 23 the wall of the chute 12 is cut away to leave an opening24, through. which the crude syrup with the debris is introduced intothe drum to fall upon the vall 21 under the said opening. Directly abovethe partition 23 is introduced a pipe 25, whereby water is sprayed orotherwise dr.-li\' ered into the drum. The motive power for rotating thegear wheel 19 and the collars 18 and 11 with the plates 20, may be ofany desired construction. hen thus constructed the operation of thefilter is as follows: The heavy liquor is introduced into the hopper 15and is conveyed downward and longitudinally through the chute 12. Onreaching the opening 2 1- the syrup falls through the same upon thecylindrical wall 21 of the drum, a certain proportion of the syruppassing immediately through the wall 21; the remainder of the syruptogether with all debris accumulates. The plates 20 are rotated, andwhen brought to the accumulation, they by means of their curved endspick up the syrup and debris and carry it slowly around the PatentedAug. 31, 1909.

drum. The plates 9.0 are perforated throughout, hence the filtration orseparation of the syrup from the debris continues, the same is beingcarried upon the plates 20.

After the plates 20 pass the horizontal position, the heavy syrup anddebris begin to travel down the incline of the said plate toward thecenter of the drum, this travel being accelerated as the plate 20 attainv the vertical, and this acceleration is likewise aided by the fact thatthe plates 20 are pre sented to the water sprayed from the pipe 525. Thepipe 25 introduces water upon the back of the said plates as they passthe vertical and move from the said pipe, and any adhering materialsare, by the water, dislodged from the plates 20.

All of the material delivered from the upper surface of the plates 20 ispassed to and delivered upon the upper surface of the partition which isinclined toward the delivery end of the chute 12. Therefore allmaterials received upon the said partition which do not pass through theperforations thereof, are delivered by the said partition to thedelivery end of the said chute. The partition receives the water fromthe pipe at all times when a plate 20 is not interposed, and thein'nnediate etlect of this is that all debris washed by the water,liberating all adhering syrup therefrom. In its final disposition thedebris is delivered from the chute 12 to receptacles designed therefor,or is delivered to a refuse station.

It will be noticed that throughout the whole of this construction, thematerial used is perforated, and therefore filtration is not arrested atany point. Also by reason of this construction the filter may be sprayedor otherwise washed from any point. As above stated the structure issuspended over a suitable receptacle to catch the d ippings from allparts of the filter.

Admission to the interior of the drum is b gained by raising a section26, hinged upon the filter in any suitable manner, that shown in the drawings being by the use of the two eye-plates 27 and 28. The section 26may be of any size, that shown in the drawing being one-half of the fullsize of the drunnand said section is held in closed position by a pin 29over which an eye-plate 30 extends.

ith the section 26 opened as shown in dotted lines at Fig. 2, and thesection 31 of the cylindrical wall, which is hinged at 32, raised, theplates 20 and the chute 12 may be withd awn from the drum; by thisconstruction the filter may be kept scrupulously clean.

Having thus described my invention. 1 claim as new and desire to secureby Letters Patent,
